About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX450-100S
The AirTAC SAIJ32X450-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 450 mm stroke that can be dialed back by up to 100 mm, creating a precise 350-450 mm usable travel window for product changeovers. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides, and the standard PT tapered port threads match the G1/8 air supply for this 32 mm bore.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX450-100S Is Used
Machine Changeover
Dial in the 350-450 mm travel window during product size changes without physically swapping the actuator or adding mechanical shims.
Variable End Stops
Fine-tune the retract position on the fly to accommodate different package lengths on a sorting line.
Light Assembly Positioning
Leverage the 402 N push force to move small jigs, using the rear screw to set exact stopping depths.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX450-100S the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa; step up to a 40 mm bore if your application requires 628 N. The adjustable stroke is ideal for fine-tuning end positions at commissioning without swapping cylinders or adding external stops. To replace an ISO 15552 cylinder, match the 32 mm bore, 450 mm stroke, 100 mm adjustment, PT G1/8 port, and -S magnet.
Because the 450 mm stroke is relatively long for a 32 mm rod, an external guide is recommended to prevent excessive side-loading. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac Adjustable Cylinder SAIJ32 SAIJ32AX450-100S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm. This creates a usable travel window of 350 to 450 mm, letting you fine-tune the end position without changing the cylinder.
